Objective:To investigate the clinical characteristics and prognostic factors of patients with primary nasal non-Hodgkin's lymphoma(NHL). Methods:The clinical features,diagnosis and treatment of 38 patients with NHL occurring in nasal cavities and paranasal sinuses were retrospectively analyzed. Results:The Ann Arbor stages were:stage Ⅰ,14patients; stage Ⅱ,11 patients;stage Ⅲ,7 patients;stage Ⅳ,6 patients. The most common symptoms at the presentation included nasal obstruction,rhinorrhea and cpistaxis. 11 patients had B symptoms(fever,night sweat,and/or weight loss). The lymphoma cells in all the cases ranged in size from small to large,and necrosis was common. Immunophenotyping were determined in 25cases and all were T cell type. 6 cases with early localized-disease were treated with radiotherapy and 7 had chemotherapy,the remaining 25 cases received combined chemotherapy and radiotherapy. The 5-year overall survival(OS) for the entire group was 78.9%,and those for patients with localized disease(stages Ⅰ and Ⅱ) and those with the advanced disease(stages Ⅲ and Ⅳ) were 92.0% and 53.8%,respectively(?2=11.29, P

Objective To investigate the clinical efficacy of thumbtack needle acupuncture in treating sympathetic cervical spondylosis.Methods Seventy-seven patients with sympathetic cervical spondylosis were randomly allocated to a treatment group of 37 cases and a control group of 40 cases. The same acupoints were selected in the two groups. The treatment group received thumbtack needle acupuncture and the control group, conventional acupuncture. The clinical therapeutic effects were compared between the two groups after two courses of treatment.Results The total efficacy rate was 91.9% in the treatment group and 92.5% in the control group; there was no statistically significant difference between the two groups (P>0.05).Conclusions Thumbtack needle acupuncture s is an effective way to treat sympathetic cervical spondylosis. The patients have good compliance.

ObjectiveTo investigate the insulin receptor expression binding characteristics and it's clinical significance of 125 I insulin on human hepatocllular cancer cell membrane.MethodInsulin was radioiodinated using Ch T method, isolated and purified by polyacrylamide gel electryophresis. Human hepatocellular cancer and adjacent liver tissue cell membrane were extracted, receptor binding and bind ability of 125 I insulin and insulin receptor on hepatocellular cancer and adjacent hepatic cell membrane were studied. ResultsThe specific activity of 125 I insulin was 46 1?1 2 TBq/mmol,the radiochemical purity was over 98%. Insulin receptor content increased in hepatocellular carcinoma cells 〔Bmax=(1 9?0 6)?pmol/mg protein, the Kd of high and low affinity was 2 1?0 6?nmol and 25?8?nmol respectively〕 compared with carcinoma adjacent hepatic cells 〔Bmax=( 1 42? 0 57)?pmol/mg protein t =0 032 P 0 05〕.ConclusionHuman hepatocellular carcinoma cells overexpress insulin receptor. A14 125 I insulin has a specific high affinity with insulin receptor on HCC cells.

Background and purpose:Studies have shown that renin-angiotensin system (RAS) is closely associated with tumor progress. angiotensinⅡ (AngⅡ) is the most important component of RAS. This study aimed to investigate the possible mechanism by which AngⅡ affected the cell proliferation in human breast cancer cell line MCF-7.Methods:CCK-8 was used to investigate the cell proliferation alteration of MCF-7 cells after treatment of AngⅡ at different dose and time. The inlfuence of losartan (an AT1R inhibitor) and PD98059 (a MAPK inhibitor) in AngⅡ-enhanced cell proliferation was detected by CCK-8. Protein expression was analyzed by Western blot.Results:AngⅡ stimulated the growth of breast cancer cells in a dose- and time-dependent manner. The maximal proliferation effect on MCF-7 cells was obtained with 10-7 mol/L AngⅡ and 24 h, respectively (P<0.000 1). Losartan signiifcantly decreased the level of AngⅡ-induced proliferative effects (P<0.05). Western blot showed that AngⅡ caused rapid activation of p-ERK. In addition, PD98059 could signiifcantly suppress AngⅡ-promoted cell proliferation.Conclusion:AngⅡ can promote MCF-7 cell proliferation through AT1R/ERK/MAPK pathway activation, which could be reversed by losartan or PD98059. Therefore, targeting AngⅡ/AT1R/MAPK signaling could be a novel therapeutic for breast cancer.

Objective To study the effects of N-acetylcysteine (NAC) on the proliferation, apoptosis and collagen synthesis of human lung fibroblast (HLF). Methods HLF was primarily cultured in complete medium of DMEM/F12. Different concentrations of NAC (5,10,20,40mmol/L) were administrated. Cell proliferations were tested by methylthiazolyltetrazolium (MTT) ,apoptosis and cell cycle were detected with Flow cytometer and mRNA and 40 mmoi/L )after 24 hours,the apoptosis rates were (34.38±5.80)%, (37.72±3.10)%, (44.05± 4.52) % and (59.18±5.24) % ) respectively, significantly higher than that of the controls (3.92±1.24) % pression of type Ⅰ procollagen in HLF was decreased significantly after administration of NAC at 5, 10,20, 40 mmol/L respectively (P < 0.01 ). Conclusion Administration of NAC induces apoptosis and directly inhibites the proliferation and the collagen synthesis of HLF.

Chronic diarrhea is a common complaint in gastroentology department,which is classified into a variety of types.While as eosinophilic gastroenteritis is a rare cause.A 50-year-old male patient was admitted with a 2-year history of diarrhea worsened for 10 months.Fasting could alleviate the diarrhea.Laboratory findings demonstrated anemia,low vitamins and minerals,fat malabsorption and abnormal D-xylose absorption test,delayed gastric emptying.According to the endoscopic biopsy of gastrointestinal mucosa,the diagnosis of eosinophilic gastroenteritis was made.Diabetic neuropathy may aggravate the symptom.The diarrhea resolved after the administration of steroids.

Objective To compare the effect of ultrafiltration method and activated carbon absorbance method on aconitine-type alkaloid (AA) content in the preparation of Yiqi Huiyang Injection (YHJ) and to evaluate the safety of YHJ by limited detrmination of diester alkaloids (DEA).Methods Acid dye colorimetry was used to detect AA content and reverse phase high performance liquid chromatography (RP-HPLC) was applied to determine the limited content of DEA. Mesaconitine, aconitine, hypaconitine were separated on a Hypersil BDS-C?18?column, with methanol and 0.05% triethylamine (70∶30) as mobile phase, wavelength at 240 nm and external standard for quantitative analysis.Results Compared with activated carbon absorbance method, the loss of AA was reduced, limited content of aconitine was within the pharmacopoeia standard method and the other two kinds of DEA were also low in YHJ prepared by ultrafiltration method.Conclusion Ultrafiltration was superior to activated carbon absorbance in the preparation of YHJ as with AA as the parameter, and the contents of DEA were very low which indicates that the toxicity of YHJ may be also low.

0.05).The differences of comprehensive scoring of QOL and scoring of factors 1,2,3 and 4(F_1,F_2,F_3 and F_4)in group A were significant as compared with those before treatment(P0.05),indicating that oral use of SRTT inhibited the aggravation of pulmonary function.The improvement of QOL in group A was superior to that in group B after treatment and the difference was significant(P

Objective To evaluate the value of computed tomography(CT)in diagnosing abdominal tuberculosis.Methods CT features of abdominal tuberculosis proven histopathologically or by antituberculous therapy in 16 cases were retrospectively analysed.There were 8 men and 8 women,the age ranged from 20 to 66 years,mean age was 36.4 years.Results The most common CT features of abdominal tuberculosis were:lymphadenectasis(n=11),mesenteric masses(n=6),ascites(n=6,all were loculated),omental thickening(n=7),bowel wall thickening(n=6),pleural fluid(n=2),and pancreatic involvement(n=1).Tuberculous lymphadenosis(mainly the mesentery and peripancreatic lymph nodes involved)had typical CT findings including circular or multilocular enhancement,calcification of lymph nodes,abdominal lymph nodes involved more than that of retroperitoneum and peritonitis(high dense ascites,patchy or nodular lesions in the mesentery and omentum,and intestinal adhesion).Conclusion CT findings in combination with clinical symptoms and laboratory test can improve the diagnosis of abdominal tuberculosis.
